Journal ArticleDOI
Europe-wide reduction in primary productivity caused by the heat and drought in 2003
Philippe Ciais,Markus Reichstein,Nicolas Viovy,A. Granier,Jérôme Ogée,Vincent Allard,M. Aubinet,Nina Buchmann,C. Bernhofer,Arnaud Carrara,Frédéric Chevallier,N. de Noblet,Andrew D. Friend,Pierre Friedlingstein,Thomas Grünwald,Bernard Heinesch,Petri Keronen,Alexander Knohl,Gerhard Krinner,Denis Loustau,Giovanni Manca,Giorgio Matteucci,Franco Miglietta,Jean-Marc Ourcival,Dario Papale,Kim Pilegaard,Serge Rambal,G. Seufert,Jean-François Soussana,María José Sanz,Ernst Detlef Schulze,Timo Vesala,Riccardo Valentini +32 more
TL;DR: An increase in future drought events could turn temperate ecosystems into carbon sources, contributing to positive carbon-climate feedbacks already anticipated in the tropics and at high latitudes.
Journal ArticleDOI
FLUXNET: A New Tool to Study the Temporal and Spatial Variability of Ecosystem-Scale Carbon Dioxide, Water Vapor, and Energy Flux Densities
Dennis D. Baldocchi,Eva Falge,Lianhong Gu,Richard J. Olson,David Y. Hollinger,Steven W. Running,P. M. Anthoni,Ch. Bernhofer,Kenneth J. Davis,Robert G. Evans,Jose D. Fuentes,Allen H. Goldstein,Gabriel G. Katul,Beverly E. Law,Xuhui Lee,Yadvinder Malhi,Tilden P. Meyers,William Munger,Walter C. Oechel,Kim Pilegaard,Hans Peter Schmid,Riccardo Valentini,Shashi B. Verma,Timo Vesala,Kell B. Wilson,S. C. Wofsy +25 more
TL;DR: The FLUXNET project as mentioned in this paper is a global network of micrometeorological flux measurement sites that measure the exchanges of carbon dioxide, water vapor, and energy between the biosphere and atmosphere.
Journal ArticleDOI

Markus Reichstein,Eva Falge,Dennis D. Baldocchi,Dario Papale,Marc Aubinet,Paul Berbigier,Christian Bernhofer,Nina Buchmann,Nina Buchmann,Tagir G. Gilmanov,A. Granier,Thomas Grünwald,Katka Havránková,Hannu Ilvesniemi,Dalibor Janouš,Alexander Knohl,Alexander Knohl,Tuomas Laurila,Annalea Lohila,Denis Loustau,Giorgio Matteucci,Tilden P.

Seufert,Francesco Primo Vaccari,Timo Vesala,Dan Yakir,Riccardo Valentini +33 more
TL;DR: In this paper, the authors analyse the effect of extrapolation of night-time values of ecosystem respiration into the daytime; this is usually done with a temperature response function that is derived from long-term data sets.
Journal ArticleDOI
Energy balance closure at FLUXNET sites
Kell B. Wilson,Allen H. Goldstein,Eva Falge,Marc Aubinet,Dennis D. Baldocchi,Paul Berbigier,Christian Bernhofer,Reinhart Ceulemans,Han Dolman,Christopher B. Field,Achim Grelle,A. Ibrom,Beverly E. Law,Andrew S. Kowalski,Tilden P. Meyers,John Moncrieff,Russell K. Monson,Walter C. Oechel,John Tenhunen,Riccardo Valentini,Shashi B. Verma +20 more
TL;DR: A comprehensive evaluation of energy balance closure is performed across 22 sites and 50 site-years in FLUXNET, a network of eddy covariance sites measuring long-term carbon and energy fluxes in contrasting ecosystems and climates as mentioned in this paper.
Book ChapterDOI
Estimates of the annual net carbon and water exchange of forests: the EUROFLUX methodology

Martin,Paul Berbigier,Christian Bernhofer,Robert Clement,Jan Elbers,André Granier,Thomas Grünwald,K. Morgenstern,Kim Pilegaard,Corinna Rebmann,W. Snijders,Riccardo Valentini,Timo Vesala +19 more
TL;DR: In this article, the authors have described the measurement system and the procedure followed for the computation of the fluxes and procedure of flux summation, including data gap filling strategy, night flux corrections and error estimation.
